Abstract
The utility model discloses a lead damper shock absorption/isolation basin type rubber supporting seat for solving the technical problem of unsatisfactory energy consumption and shock absorption capability of a basin type rubber supporting seat in the prior art. The adopted technical scheme is as follows: a lead extrusion type damper is additionally arranged in the structure of a common basin type rubber supporting seat. When a bridge or other buildings generate larger vibration due to factors such as wind power, earthquake and the like, an external force borne by the lead damper firstly acts on a piston rod, the piston rod extrudes lead in a sealed chamber to generate plastic deformation to convert vibration of the bridge or other buildings due to the factors such as the wind power, the earthquake and the like into potential energy and heat energy to finish energy conversion, and thus, the effects of energy dissipation, energy consumption and damping are achieved. A face centered cube is used as a crystallized structure of the metal lead, thus the metal lead has good plastic deformation capability and can deform under a room temperature condition and generate dynamic recovery and dynamic recrystallization. Through recovery and recrystallizaiton, strain hardening disappears, and the tissue and performance of the lead are restored to the state before deformation, therefore, no residual stress is generated.
